This laminated pamphlet is perfect to review doubles: takeout doubles, negative doubles, support doubles, penalty doubles, responsive doubles, lead redirecting doubles, redoubles.
Note from Barbara: "This summary cheat sheet cannot possibly cover all modern uses of doubles. Modern bridge is amazingly inventive and you will stumble across many other uses of the term "double" but in the meantime, this will stand you in good stead."
